How Much Does a Cup of Flour Weigh?

For that matter, what does a cup of “X” weigh? Below is a chart of weights of various ingredients from the pages of Cooks Illustrated Magazine. Most of them are straight forward, but note that different flours weigh different amounts.

If you bake a lot, weighing flour is a good idea because, depending on how heavy or light handed you are, two cups of flour can weigh between 9.5 and 11 ounces. This is why you want to get yourself a digital scale if you do not have one. Then, 10 ounces of flour is always 10 ounces of flour.

When it comes to flour, there are different kinds of flour – all purpose (AP), cake, bread and rye, to name a few. AP flour and rye flour weigh the same, bread flour is heavier and cake flour is lighter.

If a certain recipe calls for 14.5 ounces of AP flour, use that number. However, if the recipe you are using just calls for three cups of AP flour, reference the chart below and weigh out 15 ounces of flour. It’s that easy.

Update: For more on what ingredients weigh, see this recent post here.

For Flour the weight to volume ratio is usually stated on the bag.
For example on the bag of Gold Medal Better for Bread Flour it states that
“There are 3-1/3 cups flour per pound”.
My pizza dough recipe uses 2-1/2 cups flour, 12 oz. of this flour is perfect.
